13 Claims.

This invention relates to new and useful immovements in walking beams.

One Yobject of the invention is to provide an improved walking beamhaving hangers for connec- 5 tion with the usual polish rod and pitman.

An important object of the invention is to provide a hanger for awalking beam arranged to be fastened to said beam and having its endprojecting beyond the end of the beam, whereby bearing l supports for apolish rod or a pitman may be mounted thereon.

Another object of the invention is to provide a hanger for a walkingbeam comprising a pair of angular members engaging over the base flangel of the beam and secured thereto at the end of said beam, said membersbeing spaced apart by the web of the beam so that a rod supported by thehanger may depend between the members.

Still another object of the invention is to provide an improved walkingbeamwhich is provided with top and bottom reinforcing plates at itscentral portion, each plate having openings therein spaced along itslongitudinal axis, whereby welding or other material may be inserted insaid openings to rigidly secure the plates to the beam.

A further object of the invention is to provide a plurality of verticalbraces which are secured to the web and flanges of an I-beam and whichextend between the flanges of said beam, whereby k the rigidity andstrength of said beam is greatly increased.

A construction designed to carry out the invention will be hereinafterdescribed, together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawings,in which an example of the invention is shown, and wherein:

Figure 1 is a side elevation of a walking beam mounted on a Samson postand constructed in accordance with the invention,

Figure 2 is a transverse vertical sectional view taken on the line 2-2of Figure 1,

Figure 3 is a plan view of the beam and having part thereof broken awayto show one of the hangers which are secured thereto,

Figure 4 is a longitudinal, vertical sectional view of the parts shownin Figure 3,

Figure 5 is a transverse, vertical sectional view, taken on the line 5-5of Figure 3,

Figure 6 is a vertical sectional view taken on the line 6-6 of Figure 1,

Figure '7 is an isometric view of one of the hangers fastened on the endof thebeam, which is broken away, V

Figure 8 is a side elevation of a short piece of I-beam of which thebrace `members are formed.

Figure 9 is a side elevation of another form of I-beam,

Figure 10 is an isometrical, sectional view of the same,

Figure 11 is a transverse, vertical sectional view, taken on the lineII-II of Figure 10.

In the drawings the numeral I0 designates-an upright Samson post whichmay be of any suitable type. The type shown comprises four legs Ilconverging upwardly to form a pyramid. The usual bearing saddle I2 ismounted on the upper end of the post and receives the transverse fulcrumbar or rockerrl3 of a walking beam I4.

The walking beam is preferably formed of an I-beam I 5 which has itscentral portion reinforced by longitudinal plates or bars I6. The plateslie along the top and bottom of the beam and are provided with aplurality of elongated openings I1 extending therethrough. The openingsare positioned along the longitudinal axis of each plate and when saidplate is in position on the beam, these openings are in alinement withthe vertical web I5 of said beam.

Welding, or other suitable material I8 is inserted in the openings andit is obvious that since,l the openings are directly above the web, eachplate is secured by the welding to said web. If desired, each plate maybe further welded to theI beam along its edges. By providing theopenings I1, it will be seen that the plates become a part of the web ofthe beam and are not secured only to the flanges, as is the usualpractice. The beam is reinforced and its strength greatly increasedwithout the addition of a great deal to its weight.

To further brace the beam at its central portion, vertical braces I9extend between the flanges of the beam on each side of the web. Thebraces may be positioned at any points near the center of the beam andare preferably welded thereto so as to provide an integral structure. Itis pointed out that the rigidity of the beam is greatly increased and byproviding both bars I6 and braces I9, a beam of lighter weight which canwithstand greatly increased loads is formed.

On each end of the beam a hanger is provided. Each hanger comprises apair of angular bracketsf or members 2 I disposed longitudinally of thebeam and extending beyond the end thereof. Each bracket has itshorizontal member overlying the base flange of the beam I4 and abuttingthe web thereof. The vertical member depends from the horizontal membercontiguous to the base flange of the beam. I have shown the horizontalmember welded to the web and the vertical member welded to the baseflange, but the angular brackets may be fastened in any desired manner,although welding has been found satisfactory.

Vertical braces 20, similar to the braces I9, are mounted between theunderside of the top ange of the beam and the top of the inner end ofeach bracket on each side of the web. These braces are preferably weldedto the brackets, web, and top flange, and it is obvious that when a loadis placed on the outer end of the brackets, the braces 20 will preventsuch load from breaking the Weld and jerking the brackets from the beam.

On the projecting end of each hanger are mounted bearing boxes 22. O neof these boxes has the upper end of the polish rod 23 journaled therein.The other box carries the ordinary operating pitman 24 for impartingmotion from the power source (not shown) to the walking beam in theusual manner. It is pointed out that the web of the beam spaces thebrackets sumciently far apart to allow the pitman and polish rod todepend therethrough and to freely swing therein.

It will be seen that a very efficient, simple and strong hanger is thusformed. It is pointed out that any suitable means for carrying thepitman and rod may be used on thehanger. 'I'he brackets being merely apair of angular members, are very cheap, and by welding said members tothe walking beam and bracing their inner ends with the braces 20, asturdy support for the pitman and rod is provided.

on the top and bottom of the beam,

The Sampson post is provided with the customary headache post 25 on oneside and the ordinary ladder 26 on the other. At the lower end of thelegs, I provide foot plates or members 21. These plates have a tendencyto work or breathe during the swinging of the beam, due to the loadcarried by the polish rod. For overcoming this breathing, I weldtriangular brace members 28 to the plates and to the lower portion ofthe legs. These members may be formed by cutting a short piece of I-beamA diagonally, as shown in dotted lines in Figure 8.

It will be seen that the angular brackets which form each hanger arenothing more than short' pieces of angle bars and a very cheap andinexpensive structure is had. The welding of the longitudinal bars I6and the hanger to the walking beam, as well as the welding of the bracesI9 and 20 between the flange of the beam make for easy and quickassembling of the parts, and also provide a positive fastening means forthe same. It is again pointed out, however, that the invention is not tobe limited to welding, as satisfactory results may be obtained withother fastenings.

In Figures 9 to l1 I have shown another form of walking beam 30. Thisbeam is constructed of a central longitudinal bar 3| which forms the webof the beam. A pair of longitudinal, angular members 32 are secured atthe upper and lower l ends of the bar and each member has its verticalleg 33 contiguous to the bar and its horizontal leg S4 extendingoutwardly therefrom, whereby an I-beam is formed, as shown in Figures 10and 11. The flat outer side of the horizontal legs 34 of the angularmembers is slightly beyond each edge of the central bar SI, whereby acentral longitudinal groove 35 is formed in the upper and lower ends ofthe I-beam.

Thus when the reinforcing plates I6 are placed the openings I'I in theplates will be in alinement with the groove I1. The insertion of weldingI8 through the openings I1 will enter the groove, and it is obvious thatan integral structure of the plates and the beam is produced, wherebythe plates and b-eam are permanently secured together.
